Apparently Clang 14 considers the bit width of long_t::length value-dependent.
Perhaps clang::FieldDecl::getBitWidthValue() should check if the bit width is
value-dependent before calling Expr::EvaluateKnownConstInt(). Or perhaps
clang_getFieldDeclBitWidth() should check that. If you can reproduce the crash
consistently with Clang 14 (I cannot with my system Clang 13), report the bug.

Does KDevelop compiled against Clang 13 call Clang 14 implementation at runtime
or does it keep using the Clang 13 version it was compiled against?
